Can a broadcastReceiver catch multiple broadcasts?
I am trying to create multiple proximity alerts but I cant get it to work...
I think that the broadcast receiver gets overwritten and thus is handling only the last broadcast. So if I had two points close by only the one whose intent was created last will generate an alert...
I read that I should use request codes but I have no idea on how to do that...
My method for setting up the pending intents and the broadcast receiver...
private void addProximityAlert(double latitude, double longitude, String poiName, String intentfilter) {
Bundle extras = new Bundle();
extras.putString("name", poiName);
Intent intent = new Intent(PROX_ALERT_INTENT+poiName);
intent.putExtras(extras);
PendingIntent proximityIntent = PendingIntent.getBroadcast(MainMenu.this, requestCode, intent, 0);
locationManager.addProximityAlert(
latitude, // the latitude of the central point of the alert region
longitude, // the longitude of the central point of the alert region
POINT_RADIUS, // the radius of the central point of the alert region, in meters
PROX_ALERT_EXPIRATION, // time for this proximity alert, in milliseconds, or -1 to indicate no expiration
proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected
);
requestCode++;
IntentFilter filter = new IntentFilter(intentfilter);
registerReceiver(new ProximityIntentReceiver(), filter);
}
My broadcastreceiver class
public class ProximityIntentReceiver extends BroadcastReceiver {
private static final int NOTIFICATION_ID = 1000;
@Override
public void onReceive(Context context, Intent intent) {
String key = LocationManager.KEY_PROXIMITY_ENTERING;
Boolean entering = intent.getBooleanExtra(key, false);
if (entering) {
Log.d(getClass().getSimpleName(), "entering");
}
else {
Log.d(getClass().getSimpleName(), "exiting");
}
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Co开发者_JAVA技巧ntext.NOTIFICATION_SERVICE);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, null, 0);
Notification notification = createNotification();
notification.setLatestEventInfo(context,
"Proximity Alert!", "You are approaching: " +intent.getExtras().get("name"), pendingIntent);
//here-------------------------------------
notificationManager.notify(NOTIFICATION_ID, notification);
}
private Notification createNotification() {
Notification notification = new Notification();
notification.icon = R.drawable.androidmarker;
notification.when = System.currentTimeMillis();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.flags |= Notification.FLAG_INSISTENT;
notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND;
notification.ledARGB = Color.WHITE;
notification.ledOnMS = 300;
notification.ledOffMS = 1500;
return notification;
}
}
Can you please help me??? I'm really stuck with this...
Any help would be really appreciated!!!
i got it working after all...
Exactly what I was looking for: http://www.gauntface.co.uk/blog/2010/01/04/proximity-alerts-in-android/
Modifications I made
private void addProximityAlert(double latitude, double longitude, String poiName) {
Bundle extras = new Bundle();
extras.putString("name", poiName);
extras.putInt("id", requestCode);
Intent intent = new Intent(PROX_ALERT_INTENT);
intent.putExtra(PROX_ALERT_INTENT, extras);
PendingIntent proximityIntent = PendingIntent.getBroadcast(MainMenu.this, requestCode , intent, PendingIntent.FLAG_CANCEL_CURRENT);
locationManager.addProximityAlert(
latitude, // the latitude of the central point of the alert region
longitude, // the longitude of the central point of the alert region
POINT_RADIUS, // the radius of the central point of the alert region, in meters
PROX_ALERT_EXPIRATION, // time for this proximity alert, in milliseconds, or -1 to indicate no expiration
proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected
);
requestCode++;
}
private void initializeReceiver()
{
IntentFilter filter = new IntentFilter(PROX_ALERT_INTENT);
registerReceiver(new ProximityIntentReceiver(), filter);
}
